液晶调谐等离激元诱导透明与法布里腔杂化模式的滤波器
摘要：
本发明涉及一种液晶调谐等离激元诱导透明与法布里腔杂化模式的滤波器，包括两片各覆盖一层氧化铟锡ITO膜的玻璃，以及组装在两片玻璃之间的液晶，液晶厚度为1μm，两层ITO膜分别称为T1膜和T2膜，T1膜的膜厚为T1＝970nm；在T1膜与玻璃之间还镀有厚度50nm的Au膜；在T1膜上制作有周期性排布的金属-电介质-金属型MIM纳米棒阵列；沿MIM纳米棒长轴方向周期为500nm，沿其短轴方向周期为300nm，每个MIM纳米棒单元的材料为Au-SiO2-Au，MIM纳米棒长度为125nm，宽度为50nm，上下两层Au厚度分别为30nm，中间SiO2厚度为20nm。
摘要（英）：

The invention discloses a filter adopting a LC (liquid crystal)-tuned PIT (plasmon induced transparency) and FP (Fabry-Perot) cavity hybrid mode. The filter comprises two pieces of glass and an LC assembled between the two pieces of glass, wherein each of the two pieces of glass is covered with an ITO (indium tin oxide) film; the LC is 1 mu m thick, the two ITO films are a T1 film and a T2 film respectively, and the thickness of the T1 film is 970 nm; an Au film with the thickness of 50 nm is plated between the T1 film and the glass; a periodically arranged MIM (metal-insulator-metal) nanorodarray is made on the T1 film; the cycle in the long axis direction of MIM nanorods is 500 nm, and the cycle in the short axis direction of the MIM nanorods is 300 nm; each MIM nanorod unit is made ofAu-SiO2-Au, each MIM nanorod is 125 nm long and 50 nm wide, the Au thickness of upper and lower layers is 30 nm, and the middle SiO2 thickness is 20 nm.
